Operation or Process

A description is given below of processes or operation according to the present embodiment.

Process of Registering Schedule

A process in which a user A (e.g., Taro Ricoh) registers a his or her schedule with the schedule management server 8 from the PC 5 is described below with reference to FIG. 12 to FIG. 15. FIG. 12 is a sequence diagram illustrating a process of registering a schedule, according to the present embodiment. FIG. 13 is an illustration of a sign-in screen, according to the present embodiment. FIG. 15 is an illustration of a screen for inputting a schedule, which is hereinafter, also referred to as a schedule input screen, according to the present embodiment.

When the user A operates, for example, the keyboard 511 of the PC 5, the display control unit 54 of the PC 5 causes the display 508 to display a sign-in screen 530, which is illustrated in FIG. 13, for sign-in (Step S11). The sign-in screen 530 has an input field 531 for inputting a user ID and organization ID of a user, an input field 532 for inputting a password, a sign-in button 538 to be pressed to sign in, and a cancel button 539 to be pressed to cancel the sign-in. In the example of the present embodiment, the user ID and the organization ID is an electronic mail (E-mail) address of the user A. A part of the e-mail address indicating a user name is the user ID, and another part of the e-mail address indicating a domain name is the organization ID. Note that the input field 531 may have a field for inputting a user ID and another field for inputting an organization ID separately, instead of inputting an e-mail address.

Subsequently, when the user A inputs his or her user ID and organization ID in the input field 531, enters his or her password in the input field 532, and presses the sign-in button 538, the receiving unit 52 receives a sign-in request for sign-in (Step S12). Subsequently, the transmission and reception unit 51 of the PC 5 transmits, to the schedule management server 8, sign-in request information indicating the sign-in request (Step S13). The sign-in request information includes the information (i.e., the user ID, the organization ID, and the password) received in S12. Accordingly, the transmission and reception unit 81 of the schedule management server 8 receives the sign-in request information.

Subsequently, the authentication unit 82 of the schedule management server 8 authenticates the user A using the user ID, the organization ID, and the password (Step S14). More specifically, the writing and reading unit 89 refers the user authentication management DB 8001 (see FIG. 9A) to search for a set of a user ID, an organization ID, and a password corresponding to the user ID, organization ID, and the password that are received in S13. When there is the corresponding set, the authentication unit 82 determines that the user A, who is a source of the request, is an authorized user. When there is no corresponding set, the authentication unit 82 determines that the user A is not an authorized (unauthorized) user. When the user A is not an authorized user, the transmission and reception unit 81 transmits, to the PC 5, a notification indicating that the user A is not an authorized user. In the following, an example in which the user A is an authorized user described.

Subsequently, the transmission and reception unit 81 transmits an authentication result to the PC 5 (Step S15). Accordingly, the transmission and reception unit 51 of the PC 5 receives the authentication result.

Subsequently, the display control unit 54 of the PC 5 causes the display 508 to display an initial screen 540, which is illustrated in FIG. 14 (Step S16). The initial screen 540 has a “register schedule” button 541 for registering a schedule and a “check action item” button 542 for viewing action items. When the user presses the “register schedule” button 541, the receiving unit 52 receives a schedule registration (Step S17). Subsequently, the transmission and reception unit 51 transmits a schedule registration request to the schedule management server 8 (Step S18). Accordingly, the transmission and reception unit 81 of the schedule management server 8 receives the schedule registration request.

Subsequently, the writing and reading unit 89 of the schedule management server 8 searches the user management DB 8002 (see FIG. 9B) using the organization ID received in S13 as a search key and reads all user IDs and all user names corresponding to the search key (Step S19). Then, the transmission and reception unit 81 transmits schedule input screen information to the PC 5 (Step S20). The schedule input screen information includes all user IDs and all user names that are read in S19. All user names include a user name of the user A who made a reservation and who input for the sign-in in S12. Accordingly, the transmission and reception unit 51 of the PC 5 receives the schedule input screen information.

Subsequently, the display control unit 54 of the PC 5 causes the display 508 to display a schedule input screen 550, which is illustrated in FIG. 15 (Step S21).

The schedule input screen 550 includes an input field 551 for inputting an event name, an input field 552 for inputting a shared resource ID or a shared resource name, an input field 553 for inputting a scheduled event start date and time (date and time for starting using a shared resource), an input field 554 for inputting a scheduled event end date and time (date and time for ending using a shared resource), an input field 555 for entering a memo such as an agenda, a display field 556 for displaying a name of a user who makes a reservation, a selection menu 557 for selecting participants other than the user who makes a reservation, an “OK” button 558 to be pressed to register the reservation, and a “CANCEL” button 559 to be pressed to cancel the inputs. The user name of a user who makes a reservation is the name of the user who inputs for the sign-in using the PC 5 in S12. In addition, a mouse pointer p1 is also displayed.

It should be noted that an e-mail address may be entered in the input field 552. In addition, when a shared resource name is selected in the selection menu 557, the shared resource is also added as a participant.

Subsequently, when the user A inputs an item in each of the input fields 551 to 555, selects names of users (user names), who are desired participants of the meeting, from the selection menu 557 by using the pointer p1, and presses the “OK” button 558, the receiving unit 52 receives the inputs of schedule information (Step S22). Subsequently, the transmission and reception unit 51 transmits the schedule information to the schedule management server 8 (Step S23). The schedule information includes an event name, a shared resource ID (or a share resource name), a scheduled start date and time, a scheduled end date and time, a user ID of each participant, and a memo. When a shared resource ID is entered in the input field 552 on the schedule input screen 550, the shared resource ID is transmitted, and when a shared resource name is entered in the input field 552, the shared resource is transmitted. On the schedule input screen 550, the user name is selected in the selection menu 557, but since the user ID is also received in S20, the user ID corresponding to the user name is transmitted. Accordingly, the transmission and reception unit 81 of the schedule management server 8 receives the schedule information.

Subsequently, the writing and reading unit 89 of the schedule management server 8 searches the shared resource management DB 8003 (see FIG. 9C) using the shared resource ID (or shared resource name) received in S23 as a search key and reads a shared resource name (or a shared resource ID) corresponding to the search key (Step S24).

Subsequently, the writing and reading unit 89 stores the reservation information in the shared resource reservation management DB 8004 (see FIG. 10A) (Step S25). In this case, the writing and reading unit 89 adds one record of the reservation information to the shared resource reservation management table of the shared resource reservation management DB 8004 managed by a scheduler registered in advance. The reservation information is configured based on the schedule information received in S23 and the shared resource name (or shared resource ID) read in S24. In addition, the scheduled use start date and time in the shared resource reservation management DB 8004 corresponds to the scheduled start date and time in the schedule information. In addition, the scheduled use end date and time in the shared resource reservation management DB 8004 corresponds to the scheduled end date and time in the schedule information.

In addition, the writing and reading unit 89 stores the plan information in the event management DB 8005 (see FIG. 10B) (Step S26). In this case, the writing and reading unit 89 adds one record of the plan information to the event management table of the event management DB 8005 managed by a scheduler registered in advance. The plan information is configured based on the schedule information received in S23. In addition, the scheduled event start date and time in the event management DB 8005 corresponds to the scheduled start date and time in the schedule information. In addition, the scheduled event end date and time in the event management DB 8005 corresponds to the scheduled end date and time in the schedule information.

As described above, the user A registers his or her schedule with the schedule management server 8.

Process of Starting Event

A process in which the user A (e.g., Taro Ricoh) holds a meeting with other participants using the electronic whiteboard 2 in the meeting room X that is reserved by the user A in advance is described below with reference to FIG. 16 to FIG. 21. FIG. 16 and FIG. 18 are sequence diagrams each of which illustrates a process of starting an event, according to the present embodiment. FIG. 17 is an illustration of a shared resource reservation list screen, according to the present embodiment. FIG. 19 is an illustration of a project list screen, according to the present embodiment. FIG. 20 is an illustration of a detail information screen for an event, according to the present embodiment. FIG. 21 is an illustration for explaining a use scenario of the electronic whiteboard 2, according to the present embodiment.

First, when a user presses the power switch 222 of the electronic whiteboard 2, the receiving unit 22 of the electronic whiteboard 2 receives power on (Step S31). Subsequently, the transmission and reception unit 21 transmits sign-in request information indicating a sign-in request to the sharing support server 6 (Step S32). In this example, when the user simply presses the power switch 222, the transmission and reception unit 21 automatically transmits the sign-in request information. The sign-in request information includes time zone information associated with a country or a region in which the electronic whiteboard 2 is located, a user ID, an organization ID, and a password of a user of the communication terminal (in this example, the electronic whiteboard 2). Accordingly, the transmission and reception unit 61 of the sharing support server 6 receives the sign-in request information.

Subsequently, the authentication unit 82 of the schedule management server 8 authenticates the user A using the user ID, the organization ID, and the password (Step S34). More specifically, the writing and reading unit 69 refers the user authentication management DB 6001 (see FIG. 7A) to search for a set of a user ID, an organization ID, and a password, using the user ID, the organization ID, and the password that are received in S33 as a search key. When there is the corresponding set, the authentication unit 82 determines that the user A, who is a source of the request, is an authorized user. When there is no corresponding set, the authentication unit 82 determines that the user A, who is a source of the request, is not an authorized (unauthorized) user. When the user A is not an authorized user, the transmission and reception unit 61 transmits, to the electronic whiteboard 2, a notification indicating that the user A is not an authorized user. In the following, an example in which the user A is an authorized user is described.

Subsequently, the writing and reading unit 69 of the sharing support server 6 searches the access management DB 6002 (see FIG. 7B) using the organization ID received in S32 as a search key and reads an access ID and an access password corresponding to the search key (Step S34).

Subsequently, the transmission and reception unit 61 transmits, to the schedule management server 8, reservation request information indicating information on a request for shared resource reservation information and plan request information indicating information on a request for plan information of the user (Step S35). The reservation request information and the plan request information include the time zone information and the user ID and the organization ID of a user of a communication terminal received in S32, and the access ID and the password read in S34. Accordingly, the transmission and reception unit 81 of the schedule management server 8 receives the reservation request information and the plan request information.

Subsequently, the authentication unit 82 of the schedule management server 8 authenticates the sharing support server 6 using the access ID and the access password (Step S36). More specifically, the writing and reading unit 89 refers the server authentication management DB 8006 (see FIG. 11A) to search for a pair of an access ID and an access password corresponding to the access ID and the access password that are received in S35. When there is the corresponding pair, the authentication unit 82 determines that the access of the sharing support server 6, which is a source of the request, is authorized. When there is no corresponding pair, the authentication unit 82 determines that the access of the sharing support server 6, which is a source of the request, is not authorized. When the access of the sharing support server 6 is not authorized, the transmission and reception unit 81 transmits, to the sharing support server 6, a notification indicating that the access is not authorized. In the following, an example in which the access is authorized is described.

Subsequently, the writing and reading unit 89 of the schedule management server 8 searches the shared resource reservation management DB 8004 (see FIG. 10A), which is managed by the scheduler specified in the above, using the user ID of a user of a communication terminal received in S35 as a search key and reads reservation information corresponding to the search key (Step S37). In this example, the writing and reading unit 89 reads the reservation information of which the scheduled use start date and time indicates today.

In addition, the writing and reading unit 89 searches the event management DB 8005 (see FIG. 10B), which is specified in the above, using the user ID of a user of a communication terminal received in S35 as a search key and reads plan information corresponding to the search key (Step S38) In this example, the writing and reading unit 89 reads the plan information of which scheduled event start date and time indicates today. When the schedule management server 8 is located in a country or a region different from the communication terminal such as the electronic whiteboard 2, the time zone is adjusted according to the country or the region where the communication terminal is installed and located, based on the time zone information.

Subsequently, the writing and reading unit 89 searches the project member management DB 8007 (see FIG. 11B) using the user ID of a user of a communication terminal received in S35 as a search key and reads all project IDs and project names corresponding to the search key, namely all project IDs and project names including the user ID of a user of a communication terminal (Step S39).

Subsequently, the transmission and reception unit 81 transmits, to the sharing support server 6, the reservation information read in S37, the plan information read in S38, and all project IDs and all project names read in S39 (Step S40). Accordingly, the transmission and reception unit 61 of the sharing support server 6 receives the reservation information, the plan information, and all project IDs and all project names.

Subsequently, the preparation unit 63 of the sharing support server 6 generates a reservation list based on the reservation information and the plan information received in S40 (Step S41). Subsequently, the transmission and reception unit 61 transmits reservation list information indicating content of the reservation list, all project IDs, and all project names to the electronic whiteboard 2 (Step S42). Accordingly, the transmission and reception unit 21 of the electronic whiteboard 2 receives the reservation list information, all project IDs, and all project names.

Subsequently, the display control unit 24 of the electronic whiteboard 2 causes the display 220 to display a reservation list screen 230, which is illustrated in FIG. 17 (Step S43). The reservation list screen 230 has a display area 231 for displaying a shared resource name (in this example, a name of place) and a display area 232 for displaying a date and time of today. In addition, on the reservation list screen 230, event information 235, 236, 237, etc. indicating events that utilize today's shared resource (in this example, the meeting room X) are displayed. The event information includes, for each event, a scheduled use start time to start using the shared resource and a scheduled use end time to end using the shared resource, an event name, and a user ID of a user who made a reservation. The event information includes start buttons 235 s, 236 s, 237 s, etc., which are to be pressed to identify an event to be started by the user.

Subsequently, in FIG. 18, when the user A presses the start button 235s by using, for example, the electronic pen 2500, the receiving unit 22 receives the selection of an event indicated by the event information 235 (Step S51). Then, the display control unit 24 causes the display 220 to display a project list screen 240, which is illustrated in FIG. 19, based on the project ID and the project name received in S42 (Step S52). The project list screen 240 has project icons 241 to 246 each of which indicates a project. In addition, the project list screen 240 has an “OK” button 248 to be pressed to confirm a selected project icon, and a “CANCEL” button 249 for canceling the selection of the project icon.

Subsequently, in FIG. 19, when the user A presses the project icon 241 by using, for example, the electronic pen 2500, the receiving unit 22 receives the selection of a project indicated by the project icon 241 (Step S53).

Subsequently, the transmission and reception unit 21 of the electronic whiteboard 2 transmits, to the sharing support server 6, the planned event ID selected in S51 and the project ID of the project selected in S53 (Step S54). Accordingly, the transmission and reception unit 61 of the sharing support server 6 receives the selected planned event ID and the selected project ID.

Subsequently, the generating unit 64 of the sharing support server 6 generates a unique executed event ID (Step S55). Then, the writing and reading unit 69 manages the executed event ID generated in S55, the planned event ID received in S54, the user ID and organization ID of the user who makes a reservation, and the event information, in association with each other (Step S56). Note that the user ID and organization ID of the user who makes a reservation and the event information are IDs and information based on the reservation information and the plan information received in S40. At this time point, there is no entry in the field for information on the participation (i.e., the presence or absence) of each user, namely indicating whether each user attends the meeting or not, in the plan management table (see FIG. 7C).

Subsequently, the writing and reading unit 69 manages the project ID received in S54 and the executed event ID generated in S55, in association with each other (Step S57). Then, the transmission and reception unit 61 transmits the executed event ID generated in S55 to the electronic whiteboard 2 (Step S58). Accordingly, the transmission and reception unit 21 of the electronic whiteboard 2 receives the executed event ID.

Subsequently, the writing and reading unit 29 of the electronic whiteboard 2 stores the executed event ID in the memory 2000 (Step S59). Then, the display control unit 24 causes the display 220 to display a detail information screen 250, which is illustrated in FIG. 20, including detail information on the event selected (Step S60). The detail information screen 250 for an event includes a display area 251 for displaying an event name, a display area 252 for displaying a scheduled date and time to carry out an event (scheduled start time and scheduled end date and time), and a display area 253 for displaying a name of a user who made a reservation. In addition, the detail information screen 250 for an event displays a display area 256 for displaying content of the memo and a display area 257 for displaying the prospective participant names. In the display area 257, the names of the user who makes a reservation and the other participants, which are indicated in FIG. 15, are displayed, and also check boxes for each user to confirm whether each user actually attends the meeting are displayed. The detail information screen 250 for an event also has, in a lower right part, a “close” button 259 for closing the detail information screen 250.

Subsequently, when the user inputs a check in a check box of a user who actually participates in the event, and presses the “close” button 259, the receiving unit 22 receives the selection of the participation (Step S61). Then, the transmission and reception unit 21 transmits the user ID of each user who is a prospective participant and information on the participation (i.e., the presence or absence) of each user, namely indicating whether each user attends the meeting or not, to the sharing support server 6 (Step S62). Accordingly, the transmission and reception unit 61 of the sharing support server 6 receives the user name of each who is a prospective participant and information on the participation (i.e., the presence or absence) of each user, namely indicating whether each user attends the meeting or not.

Subsequently, in the sharing support server 6, information on the participation (i.e., the presence or absence) of each user, namely indicating whether each user attends the meeting or not, is stored in the plan management DB 6003, namely managed by inputting the information in the corresponding fields, in which inputs have not been made yet. (Step S63).

As described above, the user A starts the event (in this example, the policy decision meeting) using the share resource (in this example, the meeting room X) and the communication terminal (in this example, the electronic whiteboard 2). As illustrated in FIG. 21, the user A can hold the meeting using the electronic whiteboard 2 in the meeting room X. It should be noted that the display control unit 24 displays in the upper right area of the display 220 the remaining time to use the shared resource. In this example, the display control unit 24 displays a period of time (remaining time) between the current time and the scheduled end time indicated by the event information selected in S51.

In addition, the display control unit 24 displays an icon rl to be pressed for registering an action item and an icon r2 to be pressed for checking an action item.

Process of Registering Action Item

A process of registering an action item is described below with reference to FIG. 22 to FIG. 25. FIG. 22 is a sequence diagram illustrating a process of registering an action item, according to the present embodiment. FIG. 23 is an illustration of a screen for displaying an action item, according to the present embodiment. FIG. 24 is an illustration of a screen for displaying a list of prospective executors of an action item, according to the present embodiment. FIG. 25 is an illustration of a screen for displaying a calendar for selecting a due date of an action item.

First, in FIG. 21, when the user presses the icon rl, the receiving unit 22 receives a request to register an action item (action item registration request) (Step S71). Subsequently, as illustrated in FIG. 23, when the user uses the electronic pen 2500 to draw an action item (in this example, “submit minutes”) on a drawing screen 260 a of the electronic whiteboard 2 and then to circle, or enclose with the line 262 to generate the identified area, an image (drawn image) 261 that is content of and action item, the receiving unit 22 receives the identified area including the image 261, and the recognition unit 26 recognizes the image 261 included in the identified area (Step S72).

Subsequently, as illustrated in FIG. 24, the display control unit 24 displays a prospective executor list 265 indicating a list of prospective executors of the action item on a drawing screen 260b (Step S73). Subsequently, when the user selects an executor of the action item by using the electronic pen 2500, the receiving unit 22 receives the selection of the executor of the action item (Step S74).

Subsequently, as illustrated in FIG. 25, the display control unit 24 displays a calendar 267 for receiving a due date of execution of the action item on a drawing screen 260 c (Step S75). Subsequently, when the user selects the due date by using the electronic pen 2500, the receiving unit 22 receives the selection of the due date (Step S76). The calendar 267 is an example of a due date setting screen. The due date setting screen may be a date list or the like in which days of the week etc. are not described.

Subsequently, the transmission and reception unit 21 transmits action item registration request information indicating the action item registration request to the sharing support server 6 (Step S77). The action item registration request information includes the executed event ID indicating an event in which the action item is generated, the user ID of the executor of the action item selected in S74, the image data of the action item recognized in S72 (in this example, the image data of “submit minutes”) and the due date of the action item received in S76. That is, the transmission and reception unit 21 transmits the image data in the predetermined area as image data indicating the content of the action item, which is generated in the executed event. Accordingly, the transmission and reception unit 61 of the sharing support server 6 receives the action item registration request information. When a target of the registration request is a sub action item, the action item ID for identifying a main action item related to the sub action item is included. A detailed description of the sub action item is deferred.

Subsequently, the writing and reading unit 69 of the sharing support server 6 searches the executed event management DB 6004 using the executed event ID received in S77 as a search key and reads a project ID corresponding to the search key (Step S78).

Subsequently, the generating unit 64 generates an action item event ID unique to the action item for identifying the action item (Step S79). Then, the writing and reading unit 69 manages, in the action item management DB 6005, for each executed event 1D received in S77, the user ID of the executor of the action item, the due date, and the action item ID received in S79, in association with each other (Step S80). When the main action item ID is received in S77, the writing and reading unit 29 also associates the main action item ID to be managed.

Subsequently, the writing and reading unit 69 searches the user authentication management DB 6001 using the user ID of an executor of the action item as a search key and reads an organization ID corresponding to the search key (Step S81).

Subsequently, the writing and reading unit 69 searches the access management DB 6002 using the organization ID read in S81 as a search key and reads an access ID and an access password corresponding to the search key (Step S82). Subsequently, the generating unit 64 generates a URL, which is a storage destination (location) of the image data indicating the content of the action item (Step S83). In this example, the generated URL of the image data is stored in the action item management DB 6005 by the writing and reading unit 69.

Subsequently, the transmission and reception unit 61 transmits action item registration request information indicating an action item registration request to the schedule management server 8 (Step S84). The action item registration request information includes the project ID read in S78, the user ID of an executor of the action item received in S77, the URL of the image data of the action item generated in S83, and the due date and the image data of the action item received in S77, and an access ID and an access password read in S82. Accordingly, the transmission and reception unit 81 of the schedule management server 8 receives the action item registration request information.

Subsequently, the authentication unit 82 of the schedule management server 8 authenticates the sharing support server 6 using the access ID and the access password (Step S85). Since the authentication processing is substantially the same as the processing of S36 described above, a redundant description thereof is omitted. The following describes an example in which a result of the authentication includes the information indicating that the sharing support server 6 is authorized.

The writing and reading unit 89 stores, in the action item management DB 8008, each type of data (information) received in S84 (Step S86). As a result, the schedule management server 8 manages data same as that of the sharing support server 6.

Subsequently, the transmission and reception unit 81 transmits the image data to the sharing support server 6 (Step S98). Accordingly, the transmission and reception unit 61 of the sharing support server 6 receives the image data.

Subsequently, the writing and reading unit 69 of the sharing support server 6 searches the user authentication management DB 6001 using the user ID of the executor of the action item, which is read in S94, as a search key and reads a user name corresponding to the search key (Step S99). Then, based on the image data received in S98, the user name read in S99, the due date and the main action item ID read in S94, the preparation unit 63 generates an action item list screen (Step S100).

Subsequently, the transmission and reception unit 61 transmits action item list image data to the electronic whiteboard 2 (Step S101). Accordingly, the transmission and reception unit 21 of the electronic whiteboard 2 receives the action item list image data.

Subsequently, the display control unit 24 of the electronic whiteboard 2 causes the display 220 to display an action item list screen 280, as illustrated in FIG. 27. On the action item list screen 280, a name of an executor of each action item and a due date are displayed for each of the action item images 281 to 284. In addition, on the action item list screen 280, pieces of hierarchy information 281L and 283L indicating relationship between each main action item and the corresponding sub action item is displayed. For example, an image 282 indicating “submit minutes” is an image originally designated by the electronic pen 2500 as illustrated in FIG. 23, and furthermore, is subsidiary in relation to the image (action item image) 281 indicating “prepare summarized document”. In addition, at the right of the main action item images 281 and 283, addition buttons 281 p and 284 p to be pressed when a sub action item is added are displayed.

Each of the pieces of hierarchy information 281L and 283L is an example of information representing relationship indicated by action item related information (second information). The information indicating relationship indicated by the action item related information includes letters, icons, and the like of “main”, “sub”, and the like.

As described above, the user can easily understand the relationship, the executor, and the due date of each action item.

Process of Registering Sub Action Item with Electronic Whiteboard

A process of registering a sub action item by using the electronic whiteboard 2 is described below with reference to FIG. 22, FIG. 26, and FIG. 27.

In FIG. 27, when desiring to register a sub action item for a main action item, the user presses the addition button 281 p, for example. Accordingly, in FIG. 26, the receiving unit 22 of the electronic whiteboard 2 receives the selection of the addition button 281 p (Step S103). Then, the display control unit 24 displays a drawn image as illustrated in FIG. 21 again. The user presses the icon r1 in order to register the sub action item. After that, the processing of S71 to S86 illustrated in FIG. 22 is performed. In this case, the main action item ID is transmitted in S77, and the main action item ID is associated to be managed in S80.

Through this, an action item is registered as a sub action item.

Process of Checking Action Item with PC

A process of checking an action item with the PC 5 is described below with reference to FIG. 28 to FIG. 30. FIG. 28 is a sequence diagram illustrating a process of checking, or looking, an action item with the PC 5, according to the present embodiment. FIG. 29 is an illustration of a project list screen displayed with the PC 5, according to the present embodiment. FIG. 30 is an illustration of an action item screen displayed with the PC 5, according to the present embodiment. Since processing of S111 to S116 in FIG. 28 is substantially the same as the processing of S11 to S16 in FIG. 12, a redundant description thereof is omitted.

Subsequently, on the initial screen 540 illustrated in FIG. 14, when the user presses the “check action item” button 542, the receiving unit 52 receives a request to check, or look, an action item (action item check request) (Step S117).

Then, the transmission and reception unit 51 transmits action item check request information indicating the action item check request to the schedule management server 8 (Step S118). Accordingly, the transmission and reception unit 81 of the schedule management server 8 receives the action item check request information.

Subsequently, the writing and reading unit 89 of the schedule management server 8 searches the project member management DB 8007 using the user ID and organization ID received in S113 as a search key and reads a project ID and a project name corresponding to the search key (Step S119). Then, the transmission and reception unit 81 transmits the project ID and the project name to the PC 5 (Step S120).

Subsequently, the display control unit 54 of the PC 5 causes the display 508 to display a project list screen 570, which is illustrated in FIG. 29 (Step S121). The project list screen 570 displays similar or the same content as the project list screen 240 of FIG. 19 displayed on the electronic whiteboard 2. That is, project icons 571 to 576 and buttons 578 and 579 in FIG. 29 correspond to the project icons 241 to 246 and the buttons 248 and 249 in FIG. 19, respectively.

Subsequently, in FIG. 29, when the user A presses the project icon 571 by using, for example, the mouse 512, the receiving unit 52 receives the selection of a project indicated by the project icon 571 (Step S122).

Subsequently, the transmission and reception unit 51 of the PC 5 transmits the project ID and the project name selected in S122 to the schedule management server 8 (Step S123). Accordingly, the transmission and reception unit 81 of the schedule management server 8 receives the project ID.

Subsequently, the writing and reading unit 89 of the schedule management server 8 searches the action item management DB 8008 using the project ID received in S123 as a search key and reads information on an action item corresponding to the search key (Step S124). The information on an action item includes an action item ID, a user ID of an executor of the action item, a due date, and a storage location of image data indicating content of the action item. Subsequently, the writing and reading unit 89 reads image data indicating content of the action item from the storage location of the image data indicating content of the action item is saved (Step S125). In addition, the writing and reading unit 89 searches the user management DB 8002 using the user ID of an executor of the action item read in S124 as a search key and reads a user name corresponding to the search key (Step S126). Subsequently, the transmission and reception unit 81 transmits, to the PC 5, the action item ID, the user ID of the executor of the action item, and the due date, which are read in S124, the image data read in S125, and the user name read in S126 (Step S127). Accordingly, the transmission and reception unit 51 of the PC 5 receives the user ID and the user name of the executor of the action item, the image data of the action item, and the due date.

Then, the display control unit 54 of the PC 5 causes the display 508 to display an action item screen 580, which is illustrated in FIG. 30, based on the data (information) received in S127 (Step S128). As illustrated in FIG. 30, the action item screen 580 includes pieces of action item information 581 to 584. For example, the action item information 581 includes an image indicating the content of the action item identified in FIG. 23, the user name selected in FIG. 24, and the due date set in FIG. 25. The action item screen 580 also has, in a lower right part, a “close” button 589 for closing the action item screen 580.

As described above, the user can look and check the action items that are generated in a plurality of events within the same project.

With reference to FIG. 28, the example in which the action item is checked by the PC 5 is described above. With reference to FIG. 28, the example in which the action item is checked by the PC 5 is described above. In the substantially same manner, the action items can be checked or looked with the electronic whiteboard 2 when the user presses the icon r2 in FIG. 21.

According to the present embodiment described above, as illustrated in FIG. 23, FIG. 24, and FIG. 25, the user can set an action item, an executor of the action item, and a due date of the action item by using the electronic whiteboard 2 being used in the current meeting.

This makes sure that the action item generated in the meeting is to be performed. In addition, the user does not have to use, for example, the PC 5 to register the action item by accessing a server such as a scheduler, resulting in reduction of the workload of the user.

In addition, the relationship between a main and a sub can also be registered at the time of registering the action item, and thus, it becomes easy to understand the relationship among a plurality of action items even if the plurality of action items is generated by executing a plurality of events in one project.

In addition, as illustrated in FIG. 23, when the user merely draws the line 262 to encloses an image (in this example, “submit minutes”) 261 indicating the content of the action item drawn with the electronic pen 2500, the electronic whiteboard 2 recognizes the image 261 as the image of action item and thus, specifies the content of the action item easily.

Further, as illustrated in FIG. 24, the electronic whiteboard 2 displays the prospective executor list 265 indicating a list of prospective executors of the action item to allow the user to select one of the executors of the action item so that the user does not have to input the executor's name.

Furthermore, as illustrated in FIG. 25, the electronic whiteboard 2 displays the calendar 267 for selecting a due date of each action item to allow the user to select a due date of each action item so that the user does not have to input the due date.

Any one of the above-described operations may be performed in various other ways, for example, in an order different from the one described above.
